Gwen Stefani and Gavin Rossdale are expecting their third child together, according to multiple reports.

"It's very new and they just found out," a source told Us Weekly of the 43-year-old No Doubt singer's bun in the oven. "They're excited!"

Married since 2002, the rocker couple is already kept busy by their very fashionable sons, Kingston, 7, and Zuma, 5. And the Bush frontman also has an adult daughter, model Daisy Lowe, from a previous relationship.

Rumors that Stefani was expecting started to swirl after the ab-fab star was photographed in a bikini in the South of France last month.

The "Settle Down" singer hasn't been shy about her desire to add to her brood.

"I really, really, really wanted one about two years ago," she told Marie Claire last fall. "And it didn't really work out. So … I feel good with what we've got. Everything works out how it should. You can't plan anything, right? You can try."

A rep for Stefani has not yet responded to omg!'s request for comment.
